Replace the NSSpellChecker + regex-stub engine with harper-core 2.5.0: real subject-verb agreement, verb forms, punctuation, repetition and spelling. New harper-ffi crate (staticlib) exposes harper_check over a C ABI; the CHarper module bridges it to Swift; HarperEngine maps Harper's char spans onto UTF-16 ranges and de-dups overlapping lints. NSSpellChecker stays only as a case-preserving spelling supplement, which fixes the problemm->Problem mis-casing. Bulk apply now skips no-op suggestions. build.sh / scripts/build.sh build the universal static lib; target/ and lib/ are gitignored (regenerate via harper-ffi/build.sh).

* Returns a malloc'd, NUL-terminated UTF-8 JSON C string that the caller MUST

|
* Notes on the contract:
|
|
* - "start"/"len" are CHAR (Unicode scalar) offsets, matching harper's native
|
|
* char indexing. They are NOT byte offsets and NOT UTF-16 code-unit offsets.
|
|
* "len" = span.end - span.start (end-exclusive).
|
|
* - "replacement" is the FIRST ReplaceWith suggestion's text. If the first
|
|
* actionable suggestion is a removal, "replacement" is "" (empty string).
|
|
* - Lints with NO actionable suggestion are SKIPPED.
|
|
* - "kind" is one of: "spelling", "grammar", "punctuation", "repetition",
|
|
* "capitalization", "phrasing". Best-effort; defaults to "grammar".
|
|
*
|
|
* On a null `text`, invalid UTF-8, or any internal error/panic, returns "[]".
|
|
* Never returns NULL on a normal return path. Thread-safe.
